' PATTERN-BINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 543,777, dated July 30,1895.

Application filed April 22, 1895.

To all whom it mag concern.-

Be it known that I, WALTER L. C. NILES, a citizen of the United States,and a resident of Saugus, in the county of Essex and Commonwealth ofMassachusetts, have invented a new and useful Improvement in Pattern-Binding Machines, of which the following, taken in connection with the.accompanying drawings, is a specification.

This invention relates to improvements in machines for binding the edgesof shoe-patterns and similar devices with an edging of brass or othersuitable material.

Shoe-patterns have heretofore been made of some form of paper orcompressed pulpboard or other suitable material capable of being cut tothe required shape. As the art of pattern-making has been heretoforepracticed the pattern is first cut out on the required lines by hand,after which three separate machines are commonly employed to perform theoperations of molding the edging and fitting and securingit to thepattern. The first machine above referred to is commonly called themolding-machine, and by the operation of the same a strip of fiatsheet-brass or other suitable material of sufficient width is bentlaterally to a uniform U- shaped section. The edging so molded issubstantially straight and iscut into rods of convenient length and sosold to the trade. The next machine commonly employed is thebinding-machine, which compresses the concave edging onto the edge ofthe pattern over which it is placed by the operator with sufiicientpressure to secure the edging in position. In the operation of thebinding-machine, whenever a corner is reached upon the pattern itbecomes necessary to make a niche on the inside of the edging byremoving a substantially wedge-shaped piece, so that the edging may bebent around the corner without fullness at the corner. For the abovepurpose the third machine above referred to is commonly brought intooperation, the pattern and edging being removed from the bindingmachinefor that purpose. The third machine is commonly called a cutter, and byits operation a triangular or wedge shaped piece is cut from the(concave) side of the edging adjacenttto the pattern for the purposeabove explained. In connection with the machines flerial No. 546,618-(No model.)

above referred to it is common in the trade to employ a device formolding or bending the edging longitudinally to fit the re-entrantcurvesupon the pattern. The device commonly used for-this purpose is aconicallyshaped form. around which the edging is bent to give it thedesired curvature. Such device has heretofore been aggregated with theparts of the binding-machine, being for convenience secured to somefixed part thereof, but has never been placed in operative connectionwith any of the working parts of the binding-machine.

The foregoing brief review of the art shows that there are severalmarked objections to the heretofore-existing method by which the samehas been practiced, the most important of which would appear to be thewaste of time necessitated in changing from one machine to another, andthe waste of material in the remnants or ends'of the rods or stripsbinding one or more patterns and which are commonly utilized only asscrap metal.

The object of the present invention is to combine the functions of theseveral machines above referred to in a single machine in which thepattern may be bound from a continuous strip; and to this end itconsists of a set of molding-rolls, whereby the edging is molded to theproper lateral section, a set of bindingrolls, whereby the edging iscompressed upon the edge of the pattern, and means for feeding themolded edging from the molding-rolls to the edge of the pattern whilethe same is passing through the binding-rolls.

This invention further consists of means for forming the molded edgingupon a longitudinal curve while passing from the molding-rolls to thepattern, of the form and arrangement of the cutter, of means foradjusting the relative lateral position of the molding and bindingrolls, and of the devices and combinations of devices hereinafter morespecifically set forth and claimed. I

My invention is illustrated in the accompanying drawings, in which-Figure 1 is a side view of machine embodying the same. Fig. 2 is a topplan View with upper portion of the frame and upper shaft removed toshow underlying parts. Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4-is a parhereinbefore referred to, which are left after,

tial side view showing cutter approaching its operative position. Fig. 5is an end view.

Figs. 6 and 7 are diagrammatic views showing the edging passing from themolding-rolls to 5 the pattern. Fig. 8 is a top plan view of thefinished pattern. Fig. 9 is a partial side view showing cutter inoperative position.

Similar letters and figures of reference refer to similar partsthroughout the several views.

In the drawings, A represents a frame suitable to support the workingparts of the machine.

The binding-rolls are represented by B and B, and as shown in thedrawings are arranged as follows: The roll B is rigidly mounted upon androtates with a shaft 2, which is provided with suitable hearings in theframe A, across which it extends, being operatively connected with thepower-shaft t by the gears 5 and 6. The roll 13 is mounted upon atrunnion 7, provided with suitable hearings in the block 8, arranged toreciprocate-vertically along the vertical guide-rods 9 9, secured to theframe A. To the lower end of the block 8 is secured a rod 10, whichextends through suitable hearings in frame A, along which it is free toreciprocate vertically, being guided and held in position thereby. Asuitably-placed spring 11, conveniently consisting of a coiled springsurrounding the rod 10, and arranged to bear upon the collar 12 on saidrod, and abracket 1t on the frame A is arranged to approximate the rollsB and B with sufficient pressure to compress the sides of the edgingagainst the pattern and secure it thereto. The rod extends below theframe A, and is conveniently connected with a suitable treadle (notshown) whereby the rod 10 may be depressed against the action of thespring 11, and the rolls B and B separated for the insertion or removalof the work. A rotary motion isimparted to the roll B by suitableconnection with the power-shaft 4, the form of which as shown in thedrawings I will now describe.

The trunnion 7 carries a sprocket-wheel 15, which is connected by thesprocket-chain 16 with the sprocket-wheel 17 on the shaft 18, which isconnected by a universal joint 19 with the shaft 20, provided withsuitable bearings in the frame A and carrying a sprocketwheel 21, whichis connected by the sprocketchain 22 with the sprocket-wheel 23 on thepower-shaft 4. The shaft 18 is provided with suitable bearings in thevertically-reciprocating block 8, suitable provision being made in saidbearing to allow for the vertical movement of block 8.

Upon the frame A, adjacent to the roll 13, is mounted ahorizontally-disposed idle-roli B against which the edging is pressed bythe pattern while the pattern is passing between the rolls B andB, theroll 13 acting as a gage to keep the roll B B upon the edging and inposition to properly compress the same.

In connection with the foregoing descrip tion of the form andarrangement of the hinding-rolls, I desire to say that I do not considermy invention limited to the details of mechanism as described, for it isevident that the same maybe modified by any one of ordinary skill in.the art without any departure from the essential nature of my invention.

I will now describe the form and arrangement of the molding-rolls, asshown in the drawings.

The molding-rolls are represented by D and D, the roll D having aU-sectioned grooved, extending around its peripheral face, and theperipheral face of the roll D being provided with an annular tongue at,correspondingly shaped and arranged to engage the groove at. As shown,the tongue at is corrugated and cooperates with the groove 01 to form afeed mechanism, the arrangement being such that if the end of a strip ofsuitable material of suitable width is inserted between the rolls D andD it is forced into the groove d by the tongue (1 and fed along betweenthe roll D and D, by which it is bent laterally to shape it to aU-shaped lateral section and prepare it for application to the edge ofthe pattern.

For convenience in applying the edging to the pattern I find itdesirable to provide for changing the relative lateral position of themolding and binding rolls, which, in the form shown, is accomplished bymounting the rolls D and D upon a horizontally-swinging arm 24, swingingwith a vertical shaft 25, having suitable hearings in the frame A. Thearm 24: is supported by a suitable supporting-bed 26, over which it isfree to slide, and which is secured to or forms part of the frame A. Abracket 27, secured to or made integral with the arm 24, is projectedthrough a recess 28 (see Fig. 2) in the bed 26 and carries a shoulder29, extending along the under side of the bed 26, in which is placed aset-screw 30, arranged to bear against the bed 26 and provided with asuitable threaded bearing in the shoulder 29. By means of the set-screw30 the arm 2& may be clamped in any desired position on the bed 26.

Rotation of the rolls D and D is conveniently secured as follows: Therolls D and D are respectively mounted upon the vertical shafts 31 and32, (see Fig. 3,) which are provided with suitable hearings in the arm24:. The shafts 31 and 32 are projected through their bearings and carryupon the under side of the arm 2t the engaging-gears 33 and The shaft32, below the gear 34, carries a bevel-gear 35 in mesh with thebevel-gear 36 on the shaft 37. The shaft 37 is provided with suitablehearings in the bracket 27 and in the vertical shaft 25 with which thearm 24 is arranged to swing. Upon the shaft 37 is a sprocketwheel 38,connected by the sprocket-chain 39 with the sprocket-wheel 40 on theshaft 20, which, as hereinbefore described, is in operative connectionwith the power-shaft 4:. The sprocket-chain connection 39 will allowsuflicient play for the swinging motion of shaft 37.

I find it of great importance in machines of this class to present theedging to the pattern in a longitudinally-curved form of substantiallythe same or greater degree of curvature than the sharpest re-entrantcurve upon the pattern, for when so curved the edging can be formed toany curve on the pattern by inward pressure of the pattern toward therolls, since the pattern is held upon the outside of the curve, (seeFigs. 6 and 7,) and the curve of the edging, if not of the right degreeof curvature, must be flattened or reversed, either of which results canbe secured by an inward pressure of the pattern toward the rolls. Thereversal of the longitudinal curve of the edging occurs upon outwardcurves of the pattern, as illustrated in Fig. 7, and the flattening ofthe longitudinal curve of the edging occurs in binding a flatterre-entrant curve upon the pattern, as illustrated in Fig. 6.

To form the molded edging upon a longitudinal curve of the desireddegree of curvature I have provided the following device: Adjacent toand conveniently back of the rolls D and D upon the arm 24 is a post 42,from which is projected a rod 43, preferably bent laterally and providedwith a frictionroll 44, which is projected toward the rolls D D beyondthe normal path of the molded edging as it leaves the molding-rolls, thearrangementbeing such that the roll 44 may be engaged in the groove inthe edging, and as the edging is fed along by the molding-rolls bendsthe same around the roll D, curving the edging longitudinally toward therolls B B. The amount of the curvature given to the edging, as abovestated, may be varied by a radial adjustment of the rod 43, and'for thatpurpose the post 42 is arranged to rotate in its bearings in arm 24, anda set-screw 70' is provided. by means of which it may be clamped in therequired position. I also find it convenient to provide for alongitudinal adjustment of rod 43 by means of a set-screw 45 in post 42.

E represents the edging, which is carried by a suitable reel 47conveniently mounted adjacent to the machine, and which in practice Ihave provided with a frictional tension (not shown) to prevent theloosening of the coil of edging upon the same.

The edging E is conveniently led from the reel through a vertical slot48 in a post 49 on the arm 24, the function of said slot being to insurethe proper presentation of the edging E to the molding-rolls D and D. Iwish also to say inregard to the form and arrangement of the rolls D andDand associated mechanisms, as hereinbefore described, that I do notconsider my invention limited thereto, for in so far as I am aware ofthe art the features as hereinafter defined in the claims are broadlynew and do not depend upon the details of mechanism to distinguish themfrom the prior art; and to avoid repetition it may be said that theabove statement applies to any further description of parts hereingiven.

In connection with the description of the binding-rolls B and B, Ishould have called attention to what I term the edge dog 50, thefunction of which is to keep the edging E from springing away from theedge of the pattern when the same is turned away from the rolls B andBas, for example, in binding an outward curve.

As shown in the drawings, the edge dog 50 is arranged to reciprocatevertically along the rod 9, being secured thereto by suitable boltspassing through verticallyelongated bolt-holes in the dog 50. The dog 50is bent forward and laterally to bring its bearingpoint .into properlongitudinal and lateral position with reference to the binding-roll B,and is sustained at the proper elevation with reference to the same whenthe roll B is in operative position by means of the spring 51. The shapeof the dog 50 adjacent to its bearing-point is such that when thepattern is turned against the same in binding a re-entrant curve the dog50 is depressed out of the way against the action of spring 51.

I will now describe the form and arrangement of the cutter as shown inthe drawings.

The cutter is represented by L and is mounted upon a trunnion 60,provided with suitable bearings in the vertically-swinging arm 61mounted upon the frame A. The cutter L may be rotated by suitableconnections with the power-shaft 4, (not shown,) or independentlythereof by means of an operating handle 62, which actuates asprocket-wheel 63 connected by a sprocket-chain 64 with a sprocket 65 onthe trunnion 60. Upon one side of the cutter L, I place a table 66,which supports the pattern while the edging is being cut, and upon theother side of cutter L I place a gage 67, which regulates the depth ofthe cut made by the cutter. The table 66 and gage 67 are both secured tothe arm 61. A spring 68 is conveniently provided, which bears againstthe frame A and throws the cutter out of operative position after thecut is made. 7

As shown in the drawings, the power-shaft 4 is driven by a suitableoperating-lever 72; but it is evident that with slight variations indetails of mechanism and the addition of any suitable form of clutchmechanism for stopping and starting, the machine could be readilyadapted to be operated by power, and such changes would involve nodeparture from the essential features of my invention.

The operation of my invention as embodied in the machine of the drawingsis described as follows: A coil of edging E being placed in the reel 47,and the tension (not shown) on the reel being properly adjusted, theedging E is led through the slot 48 in post 49 and the free end insertedbetween the molding-rolls D D. The rolls D and D are then. set inrotation by means of the operating-lever 72 and the connectionshereinbefore described, and

IIO

the edging E is fed between the same and molded by the groove (Z andtongue (1. After a sufficient length of the molded edging has beenpassed through the rolls D D, the rod 43 having been radially adjustedto secure the desired degree of curvature, the wheel 44: is engaged inthe groove of the edging, and the molded edging as it passes from theroll I) D is curvedlongitudinally toward the hinding-rolls B B. As thefree end of the molding edging E approaches the rolls B B, the edge of apattern is inserted in the groove therein and the pattern and edginginserted between the binding-rolls B B. While the pattern is passingbetween the rolls B B the edging is adjusted upon the edge thereof by aninward pressure of the pattern against the curved edging, the roll Bacting as a gage to insure the proper operation of the rolls B B tocompress the edging onto the edge of the pattern. When a corner of thepattern is reached, the rotation of the molding and binding rolls isstopped and the arm 61 swung inward until the table 66 is in position tosupport the pattern, when the binding-roll B is depressed by the treadle(not shown) and the cutter still farther advanced until it is incontact-with the edging, which is backed by the idle-roll B The cutter Lis then rotated to make the cut by means of the lever 62, the gage 67regulating the depth of the same. After the cut is made the cutter isreleased and the spring GI carries it out of the way while the roll I3is allowed to rise, and the pattern and edging again held. between thebinding-rolls, which are again set in operation, and by a substantialrepetition of the operations, as hereinbefore described, the operationof binding the pattern is completed.

The operation of the several auxiliary devices has been sufficientlydescribed in connection with the description hereinbefore given. I wish,however, to say in this connection that the relative rate of rotation ofthe molding and binding rolls is such that the edging is molded and fedto the edge of the pattern at substantially the same speed that thepattern is carried between the bindingrolls.
